My company supports a product that leverages Azure EventGrid to send notifications through a webhook.
One of our customers (sensibly) is wanting to limit the range of IP addresses that they can receive notifications through.
Does EventGrid have a defined address or range of addresses that can be designated?
EventGrid has a Event Domains feature to control who can receive events. That's likely to be the closest to what you're looking for.
If you are just looking to make sure the IPs for eventgrid are open, IPs are listed in the Azure IP Ranges and Service Tags doc available at https://www.microsoft.com/en-us/download/details.aspx?id=56519 . Open it in VSCode then search for EventGrid.
